Variation in the anthropometric dimensions for estimating upper and lower body obesity

Area of Science:

• Anthropometry
• Obesity Research
• Body Composition Analysis

Background:

• Assessing body fat distribution is crucial for understanding obesity-related health risks.
• Existing anthropometric methods lack standardized criterion values for categorizing upper and lower body obesity.
• Previous literature reviews identified numerous methods but no consensus on validation.

Purpose of the Study:

• To evaluate the influence of various anthropometric methods on categorizing upper and lower body obesity.
• To compare the agreement and correlation of different waist-to-hip ratio (WHR) girth methods and a skinfold method.
• To investigate potential sex differences in the reliability of these anthropometric measurements.

Main Methods:

• Comparison of three waist girth methods (waist:iliac crest, iliac crest:hip, waist:hip) and one skinfold method.
• Study population included 119 obese women and 81 obese men.
• Statistical analyses included ANOVA, Kappa statistics for agreement, and correlation coefficients.

Main Results:

• Significant differences in waist-to-hip ratio (WHR) were observed among girth methods for women, and for the waist:hip method in men.
• The chosen WHR method significantly altered the categorization of lower, normal, and upper body obesity.
• Agreement between methods was significant for men but not for women; correlations varied by sex and method combination.

Conclusions:

• Current girth methods for estimating body fat distribution require further validation and standardization.
• Sex-specific differences exist in the reliability of anthropometric measures for obesity categorization.
• Standardized methods are essential for accurate assessment and comparison of body fat distribution in clinical and research settings.
